NuFilter™ High Performance Custom RF Filters

The NuFilter™ product line includes quick-turn custom filters and complex custom filters. We design various filter topologies such as Bandpass, Highpass, Lowpass, and Notch filters.

Our QUICKFIL program provides quotations within 24 hours with a response plot and mechanical drawing. Receive your finished filter within 2 – 3 weeks after receipt of order. This program fulfills our quick-turn methodology of filters that are moderately complex in design and within the following parameters:

  • 1 to 20 GHz
  • 5% to 28% 3 dB bandwidth
  • Up to 50 W power handling

Are your specifications outside of these parameters? Not to worry, we cater to a full spectrum of RF filters.

Our CUSTOMFIL program provides the same expertise, but caters to more design-intensive, complex orders. The lead times reflect this complexity and can be longer than 3 weeks, typically less than 8 weeks.

The Benefits of a Tunable RF Filter

Filters are a staple of RF designers everywhere, and especially in applications where the integrity of the signal cannot be compromised. When you’re only concerned about a single frequency, it’s relatively easy to add in a fixed-tuned filter.  However, it becomes slightly more difficult when you need to cover multiple frequencies and can’t just utilize

Spectral Regrowth: Stay in Your Lane

Modern communication systems are typically based on a framework of channels, where the frequency spectrum is divided into channels of a defined bandwidth and each signal is assigned to a particular channel.  This is analogous to a highway system being divided into lanes.  On a highway, it is undesirable for a car to cross into

For Some Veterans the Battle has Followed them Home

I recently had the pleasure of assisting in the leadership of an event that was aimed at building community among the local population of military veterans in the Cincinnati region. The event was an absolute success, and it reinforced in me the positive and fun environment that can be found when a group of around

Why Gallium Nitride (GaN)?

GaN technology has been improving radio frequency (RF) systems since the early 1990’s. It’s ability to support high frequency, wide bandwidths, and high-power density make it invaluable in any market requiring high performance in a small form factor. When compared with other semiconductor technologies such as Gallium Arsenide (GaAs), Laterally Diffused Metal Oxide (LDMOS), and

Multifunction RF Power Amplifiers for Space Applications

NASA envisions that data throughput and size, weight, and power consumption (SWaP) requirements levied on future space exploration vehicles due to resource constraints will necessitate that a different approach is taken for communications and radar. Rather than employing individual systems for short-range communications, long-range communications, and radar, respectively, a common architecture would need to be

High Power Switched Filter Bank Options for RF Communications and Electronic Warfare (EW) Applications

A Switched Filter Bank is a device that combines switches and filters to provide user-selectable frequency channels. Switched filter banks are beneficial to Radio Frequency (RF) communication systems and are utilized in both receivers and transmitters to reduce signal interference from harmonics, spurious emissions, strong signal interferers, and to limit noise power for optimized system
